Preface

Congratulations on your purchase from the Dimension series of Ethernet switches.

This preface introduces you to the ES-3124PWR and discusses the conventions of this User’s Guide. It also
provides information on other related documentation.

About the ES-3124PWR

The ES-3124PWR Ethernet switch is a managed switch with features ideally suited in any environment with
unshielded twisted pair (UTP) wiring. It can deliver broadband IP services to:

¾ Multi-tenant unit (MTU) buildings (hotels, motels, resorts, residential multi-dwelling units, office

buildings, educational establishments, etc.)

¾ Public facilities (convention centers, airports, plazas, train stations, etc.)

¾ Enterprises.

It can also be deployed as a mini-POP (point-of-presence) in a building basement delivering 10/100Mbps data
service over Category 5 wiring to each customer.

General Syntax Conventions

¾ This guide shows you how to configure the switch using the web configurator and CLI commands. See the

online HTML help for information on individual web configurator screens.

¾ Mouse action sequences are denoted using a comma. For example, click Start, Settings, Control Panel,

Network means first you click Start, click or move the mouse pointer over Settings, then click or move
the mouse pointer over Control Panel and finally click (or double-click) Network.

¾ “Enter” means for you to type one or more characters. “Select” or “Choose” means for you to use one of

the predefined choices.

¾ Predefined choices are in Bold Arial font.

¾ Button and field labels, links and screen names in are in Bold Times New Roman font.

¾ “e.g.” is a shorthand for “for instance”, and “i.e,” means “that is” or “in other words”.

Dimension ES-3124PWR Ethernet Switch

Chapter 1

Getting to Know the ES-3124PWR

This chapter describes the key features, benefits and applications of the ES-3124PWR.

The ES-3124PWR is a stand-alone layer 2 Ethernet switch with 24 10/100Mbps ports, two RJ-45 Gigabit (1Gbps or
1000Mbps)/mini-GBIC (Gigabit Interface Converter) combo ports for uplink, two RJ-45 Gigabit ports for stacking
and a console port and a management port for local management. A combo port contains one Gigabit port and one
slot for mini-GBIC transceiver (SPF module).

With its built-in web configurator, managing and configuring the switch is easy. From cabinet management to port­level control and monitoring, you can visually configure and manage your network via the web browser. Just click
your mouse instead of typing cryptic command strings. In addition, the switch can also be managed via Telnet, the
console port, or third-party SNMP management.

1.1 Features

The next two sections describe the hardware and firmware features of the ES-3124PWR.

1.1.1 Hardware Features

Power

The ES-3124PWR requires 100~240VAC/10A power.

PoE (Power over Ethernet)

The switch can provide power to a device (that supports PoE) such as an access point or a switch through a
10/100Mbps Ethernet port.

24 10/100 Mbps Fast Ethernet Ports

Connect up to 24 computers or switches to the 10/100Mbps auto-negotiating, automatic cable sensing (auto-MDIX)
Ethernet RJ-45 ports. All Ethernet ports support:

¾ IEEE 802.3/3u/3z/3ab standards

¾ Back pressure flow control in half duplex mode

¾ IEEE 802.3x flow control in full duplex mode

Two Gigabit Ethernet Ports for Uplink Modules

The gigabit ports allow the ES-3124PWR to connect to another WAN switch or daisy-chain to other switches.

Two Slots for Mini-GBIC Modules

The mini-GBIC (Gigabit Interface Converter) module transceivers allow flexibility in connection options. You can
use mini-GBIC transceivers for fiber connections to backbone Ethernet switches.

¾ Limit dynamic port MAC address learning ¾ Static MAC address filtering

Port Link Aggregation

The ES-3124PWR adheres to the 802.3ad standard for static and dynamic port link aggregation.

Bandwidth Control

¾ The ES-3124PWR supports rate limiting in 1Mbps increments allowing you to create different service

plans.

¾ The ES-3124PWR supports IGMP snooping enabling group multicast traffic to be only forwarded to ports

that are members of that group; thus allowing you to significantly reduce multicast traffic passing through
your switch.

¾ Broadcast storm control

Quality of Service

¾ Eight queues so you can ensure mission-critical data gets delivered on time.

¾ Follows the IEEE 802.1p priority setting standard based on source/destination MAC addresses.

STP (Spanning Tree Protocol) / RSTP (Rapid STP)

(R)STP detects and breaks network loops and provides backup links between switches, bridges or routers. It allows
a switch to interact with other (R)STP-compliant switches in your network to ensure that only one path exists
between any two stations on the network.

Cluster Management

Cluster Management allows you to manage switches through one switch, called the cluster manager. The switches
must be directly connected and be in the same VLAN group so as to be able to communicate with one another using
same cluster management implementation.

1.2 Applications

This section shows a few examples of using the ES-3124PWR in various network environments.

1.2.1 Backbone Application

In this application, the switch is an ideal solution for small networks where rapid growth can be expected in the
near future.

The switch can be used standalone for a group of heavy traffic users. You can connect computers directly to the
switch’s port or connect other switches to the ES-3124PWR.

In this example, all computers connected directly or indirectly to the ES-3124PWR can share super high-speed
applications on the Gigabit server.

Getting to Know the ES-3124PWR 1-3

Dimension ES-3124PWR Ethernet Switch

To expand the network, simply add more networking devices such as switches, routers, firewalls, print servers etc.

Figure 1-1 Backbone Application

1.2.2 Bridging Example

In this example application the switch is the ideal solution for different company departments to connect to the
corporate backbone. It can alleviate bandwidth contention and eliminate server and network bottlenecks. All users
that need high bandwidth can connect to high-speed department servers via the switch. You can provide a super­fast uplink connection by using an uplink port on the ES-3124PWR.

Moreover, the switch eases supervision and maintenance by allowing network managers to centralize multiple
servers at a single location.

Figure 1-2 Bridging Application

Full-duplex mode operation only applies to point-to-point access (for example, when attaching

the switch to a workstation, server, or another switch). When connecting to hubs, use a standard

cascaded connection set at half-duplex operation.

1-4 Getting to Know the ES-3124PWR

Dimension ES-3124PWR Ethernet Switch

1.2.3 High Performance Switched Workgroup Example

The switch is ideal for connecting two power workgroups that need high bandwidth. In the following example, use
trunking to connect these two power workgroups.

Switching to higher-speed LANs such as FDDI or ATM is not feasible for most people due to the expense of
replacing all existing Ethernet cables and adapter cards, restructuring your network and complex maintenance.

The ES-3124PWR can provide the same bandwidth as FDDI and ATM at much lower cost while still being able to
use existing adapters and switches. Moreover, the current LAN structure can be retained as all ports can freely
communicate with each other.

Figure 1-3 High Performance Switched Workgroup Application

1.2.4 IEEE 802.1Q VLAN Application Examples

This section shows a workgroup and a shared server example using 802.1Q tagged VLANs. For more information
on VLANs, see the Switch Setup and VLAN Setup chapters in this User’s Guide. A VLAN (Virtual Local Area
Network) allows a physical network to be partitioned into multiple logical networks. Stations on a logical network
belong to one group. A station can belong to more than one group. With VLAN, a station cannot directly talk to or
hear from stations that are not in the same group(s) unless such traffic first goes through a router.

Tag-based VLAN Workgroup Example

Ports in the same VLAN group share the same broadcast domain thus increase network performance through
reduced broadcast traffic. VLAN groups can be modified at any time by adding, moving or changing ports without
any re-cabling.

Figure 1-4 VLAN Workgroup Application

VLAN Shared Server Example

Shared resources such as a server can be used by all ports in the same VLAN as the server, as shown in the
following example. In this example, only ports that need access to the server need belong to VLAN 3 while they
can belong to other VLAN groups too.

Chapter 2

Hardware Installation

This chapter shows two switch installation scenarios.

2.1 Installation Scenarios

The switch can be placed on a desktop or rack-mounted on a standard EIA rack. Use the rubber feet in a desktop
installation and the brackets in a rack-mounted installation.

For proper ventilation, allow at least 4 inches (10 cm) of clearance at the front and 3.4 inches (8

cm) at the back of the switch. This is especially important for enclosed rack installations.

2.1.1 Desktop Installation Procedure

1. Make sure the switch is clean and dry.

2. Set the switch on a smooth, level surface strong enough to support the weight of the switch and the

connected cables. Make sure there is a power outlet nearby.

3. Make sure there is enough clearance around the switch to allow air circulation and the attachment of cables

and the power cord.

4. Remove the adhesive backing from the rubber feet.

5. Attach the rubber feet to each corner on the bottom of the switch. These rubber feet help protect the switch

from shock or vibration and ensure space between switches when stacking.

Figure 2-1 Attaching Rubber Feet

Do not block the ventilation holes. Leave space between switches when stacking.

Hardware Installation 2-1

Dimension ES-3124PWR Ethernet Switch

2.1.2 Rack-Mounted Installation

The switch can be mounted on an EIA standard size, 19-inch rack or in a wiring closet with other equipment.
Follow the steps below to mount your switch on a standard EIA rack using a rack-mounting kit.

1. Align one bracket with the holes on one side of the switch and secure it with the bracket screws smaller

than the rack-mounting screws.

2. Attach the other bracket in a similar fashion.

Figure 2-2 Attaching Mounting Brackets and Screws

3. After attaching both mounting brackets, position the switch in the rack by lining up the holes in the

brackets with the appropriate holes on the rack. Secure the switch to the rack with the rack-mounting
screws.

3.1.1 Console Port

For local management, you can use a computer with terminal emulation software configured to the following
parameters:

¾ VT100 terminal emulation ¾ 9600 bps

¾ No parity, 8 data bits, 1 stop bit ¾ No flow control

Hardware Connections 3-1

Dimension ES-3124PWR Ethernet Switch

Connect the male 9-pin end of the console cable to the console port of the ES-3124PWR switch. Connect the
female end to a serial port (COM1, COM2 or other COM port) of your computer.

3.1.2 Ethernet Ports

The ES-3124PWR has 10/100Mbps auto-negotiating, auto-crossover Ethernet ports. In 10/100Mbps Fast Ethernet,
the speed can be 10Mbps or 100Mbps and the duplex mode can be half duplex or full duplex (100 Mbps only).

When auto-negotiation is turned on, an Ethernet port on the ES-3124PWR switch negotiates with the peer
automatically to determine the connection speed and duplex mode. If the peer Ethernet port does not support auto­negotiation or turns off this feature, the ES-3124PWR switch determines the connection speed by detecting the
signal on the cable and using half duplex mode. When the ES-3124PWR switch’s auto-negotiation is turned off, an
Ethernet port uses the pre-configured speed and duplex mode when making a connection, thus requiring you to
make sure that the settings of the peer Ethernet port are the same in order to connect.

3.1.3 Gigabit Ports

The ES-3124PWR has four 100/1000Mbps auto-negotiating, auto-crossover Gigabit ports. The speed of the
Gigabit ports can be 100Mbps or 1000Mbps and the duplex mode can be half duplex (at 100 Mbps) or full duplex.

When auto-negotiation is turned on, a Gigabit port on the ES-3124PWR negotiates with the peer automatically to
determine the connection speed and duplex mode. If the peer Ethernet port does not support auto-negotiation or
turns off this feature, the ES-3124PWR determines the connection speed by detecting the signal on the cable and
using half duplex mode. When the ES-3124PWR’s auto-negotiation is turned off, a Gigabit port uses the pre­configured speed and duplex mode when making a connection, thus requiring you to make sure that the settings of
the peer Ethernet port are the same in order to connect.

Two Gigabit ports for uplink are paired with the two mini-GBIC slots. The switch uses up to one connection for
each pair for a total of four possible Gigabit connections (one from each of the two pairs). The mini-GBIC ports
have priority over the Gigabit ports. This means that if a mini-GBIC port and the corresponding Gigabit port are
connected at the same time, the Gigabit port will be disabled.

Default Ethernet Negotiation Settings

The factory default negotiation settings for the Ethernet ports on the ES-3124PWR switch are:

o Speed: Auto o Duplex: Auto

o Flow control: On o Link Aggregation:

Disabled

Auto-crossover

All ports are auto-crossover, that is auto-MDIX ports (Media Dependent Interface Crossover), so you may use
either a straight through Ethernet cable or crossover Ethernet cable for all Ethernet port connections. Auto­crossover ports automatically sense whether they need to function as crossover or straight ports, so crossover cables
can connect both computers and switches/hubs.

3-2 Hardware Connections

Dimension ES-3124PWR Ethernet Switch

3.1.4 Mini-GBIC Slots

These are slots for mini-GBIC (Gigabit Interface Converter) transceivers. A transceiver is a single unit that houses
a transmitter and a receiver. The ES-3124PWR does not come with transceivers. You must use transceivers that
comply with the Small Form-factor Pluggable (SFP) Transceiver MultiSource Agreement (MSA). See the SFF
committee’s INF-8074i specification Rev 1.0 for details.

You can change transceivers while the switch is operating. You can use different transceivers to connect to Ethernet
switches with different types of fiber-optic connectors.

To avoid possible eye injury, do not look into an operating fiber-optic module’s connectors.

¾ Type: SFP connection interface

¾ Connection speed: 1 Gigabit per second (Gbps)

Transceiver Installation

Use the following steps to install a mini-GBIC transceiver (SFP module).

1. Insert the transceiver into the slot with the exposed section of PCB board facing down.

2. Press the transceiver firmly until it clicks into place.

3. The switch automatically detects the installed transceiver. Check the LEDs to verify that it is functioning

properly.

3-4 Hardware Connections

Figure 3-5 Transceiver Removal Example

3.1.5 Management Port

Dimension ES-3124PWR Ethernet Switch

The MGNT (management) port is used for local management. Connect directly to this port using a STP (Shield
Twisted-Pair) cable. You can configure the switch via Telnet or the web configurator.

The default IP address of the management port is 192.168.0.1 with a subnet mask of 255.255.255.0

3.2 Rear Panel

The following figure shows the rear panel of the ES-3124PWR. The rear panel contains the ventilation holes, a
connector for external backup power supply (BPS) and the power receptacle.

Figure 3-6 ES-3124PWR Rear Panel

3.2.1 Power Connector

Make sure you are using the correct power source as shown on the panel.

To connect the power to the ES-3124PWR, insert the female end of power cord to the power receptacle on the rear
panel. Connect the other end of the supplied power cord to a 100~240VAC/10A power outlet. Make sure that no
objects obstruct the airflow of the fans (located on the side of the unit).

3.2.2 External Backup Power Supply Connector

The switch supports external backup power supply (BPS).

Hardware Connections 3-5

Dimension ES-3124PWR Ethernet Switch

The backup power supply constantly monitors the status of the internal power supply. The backup power supply
automatically provides power to the switch in the event of a power failure. Once the switch receives power from the
backup power supply, it will not automatically switch back to using the internal power supply even when the power
is resumed.

3.3 Front Panel LEDs

After you connect the power to the switch, view the LEDs to ensure proper functioning of the switch and as an aid
in troubleshooting. The front panel LEDs are as follows.

4.4 Switch Lockout

You are locked out from managing the switch if another administrator is currently logged in. You must wait until
he/she has logged out before you can log in.

Moreover, you could lock yourself (and all others) out from the switch by:

1. Deleting the management VLAN (default is VLAN 1).

2. Deleting all port-based VLANs with the CPU port as a member. The “CPU port” is the management port of

the switch.

3. Filtering all traffic to the CPU port.

4. Disabling all ports.

5. Assigning minimum bandwidth to the CPU port. If you limit bandwidth to the CPU port, you may find that the

switch performs sluggishly or not at all.

Be careful not to lock yourself and others out of the switch.

4.5 Resetting the Switch

If you lock yourself (and others) from the switch or forget the ES-3124PWR password, you will need to reload the
factory-default configuration file or reset the switch back to the factory defaults.

4-6 Introducing the Web Configurator

Dimension ES-3124PWR Ethernet Switch

4.5.1 Reload the Configuration file

Uploading the factory-default configuration file replaces the current configuration file with the factory-default
configuration file. This means that you will lose all previous configurations and the speed of the console port will
be reset to the default of 9600bps with 8 data bit, no parity, one stop bit and flow control set to none. The
password will also be reset to “1234” and the IP address to 192.168.1.1.

To upload the configuration file, do the following:

Step 1. Connect to the console port using a computer with terminal emulation software. See the chapter on

hardware connections for details.

Step 2. Disconnect and reconnect the switch’s power to begin a session. When you reconnect the switch’s power,

you will see the initial screen.

Step 3. When you see the message “Press any key to enter Debug Mode within 3 seconds”

press any key to enter debug mode.

Step 4. Type atlc after the “Enter Debug Mode” message.

Step 5. Wait for the “Starting XMODEM upload” message before activating XMODEM upload on your

terminal.

Step 6. Run the HyperTerminal program by clicking Transfer, then Receive File as shown in the following

screen.

Type a location for storing the configuration file or click

Browse to look for one.

6.4 Introduction to VLANs

A VLAN (Virtual Local Area Network) allows a physical network to be partitioned into multiple logical networks.
Devices on a logical network belong to one group. A device can belong to more than one group. With VLAN, a
device cannot directly talk to or hear from devices that are not in the same group(s); the traffic must first go
through a router.

In MTU (Multi-Tenant Unit) applications, VLAN is vital in providing isolation and security among the
subscribers. When properly configured, VLAN prevents one subscriber from accessing the network resources of
another on the same LAN, thus a user will not see the printers and hard disks of another user in the same building.

VLAN also increases network performance by limiting broadcasts to a smaller and more manageable logical
broadcast domain. In traditional switched environments, all broadcast packets go to each and every individual
port. With VLAN, all broadcasts are confined to a specific broadcast domain.

Note that VLAN is unidirectional; it only governs outgoing traffic.

See the VLAN chapter for information on port-based and 802.1Q tagged VLANs.

6.5 IGMP Snooping

IGMP (Internet Group Multicast Protocol) is a session-layer protocol used to establish membership in a multicast
group - it is not used to carry user data. Refer to RFC 1112 and RFC 2236 for information on IGMP versions 1
and 2 respectively.

A switch can passively snoop on IGMP Query, Report and Leave (IGMP version 2) packets transferred between
IP multicast routers/switches and IP multicast hosts to learn the IP multicast group membership. It checks IGMP
packets passing through it, picks out the group registration information, and configures multicasting accordingly.
IGMP snooping allows the switch to learn multicast groups without you having to manually configure them.

The switch forwards multicast traffic destined for multicast groups (that it has learned from IGMP snooping or
that you have manually configured) to ports that are members of that group. The switch discards multicast traffic
destined for multicast groups that it does not know. IGMP snooping generates no additional network traffic,
allowing you to significantly reduce multicast traffic passing through your switch.

using GARP. Declarations are withdrawn by issuing a Leave message. A Leave All message terminates all
registrations. GARP timers set declaration timeout values. See the chapter on VLAN setup for more background
information.

Each port has a Join Period timer. The allowed Join Time range is between 100
and 65535 milliseconds; the default is 200 milliseconds. See the chapter on
VLAN setup for more background information.

milliseconds. Each port has a single Leave Period timer. Leave Time must be two
times larger than Join Timer; the default is 600 milliseconds.

The switch has 8 physical queues that you can map to the 8 priority levels. On the switch, traffic assigned to higher
index queues gets through faster while traffic in lower index queues is dropped if the network is congested.

See also Queuing Method and 802.1p Priority in Port Setup for related information.

Priority Level (The following descriptions are based on the traffic types defined in the IEEE 802.1d standard (which
incorporates the 802.1p).

Level 7 Typically used for network control traffic such as router configuration messages.

Level 6 Typically used for voice traffic that is especially sensitive to jitter (jitter is the variations in delay).

Level 5 Typically used for video that consumes high bandwidth and is sensitive to jitter.

Level 4

Level 3

Level 2 This is for “spare bandwidth”.

Level 1

Level 0 Typically used for best-effort traffic.

Typically used for controlled load, latency-sensitive traffic such as SNA (Systems Network
Architecture) transactions.

Typically used for “excellent effort” or better than best effort and would include important business
traffic that can tolerate some delay.

This is typically used for non-critical “background” traffic such as bulk transfers that are allowed but
that should not affect other applications and users.

Active Select this check box to enable a port. The factory default for all ports is enabled. A port must be

enabled for data transmission to occur.

Name Enter a descriptive name that identifies this port.

Type This field displays 10/100M for an Ethernet/Fast Ethernet connection and 100/1000M for Gigabit

Speed/Duplex Select the speed and the duplex mode of the Ethernet connection on this port. Choices are Auto,

10M/Half Duplex, 10M/Full Duplex, 100M/Half Duplex, 100M/Full Duplex and 1000M/Full
Duplex (for Gigabit ports only).

Selecting Auto (auto-negotiation) makes one Ethernet port able to negotiate with a peer
automatically to obtain the connection speed and duplex mode that both ends support. When auto­negotiation is turned on, an Ethernet port on the switch negotiates with the peer automatically to
determine the connection speed and duplex mode. If the peer Ethernet port does not support auto­negotiation or turns off this feature, the switch determines the connection speed by detecting the
signal on the cable and using half duplex mode. When the switch’s auto-negotiation is turned off, an
Ethernet port uses the pre-configured speed and duplex mode when making a connection, thus
requiring you to make sure that the settings of the peer Ethernet port are the same in order to
connect.

Flow Control A concentration of traffic on a port decreases port bandwidth and overflows buffer memory causing

packet discards and frame losses. Flow Control is used to regulate transmission of signals to
match the bandwidth of the receiving port.

The switch uses IEEE802.3x flow control in full duplex mode and backpressure flow control in half
duplex mode.

IEEE802.3x flow control is used in full duplex mode to send a pause signal to the sending port,
causing it to temporarily stop sending signals when the receiving port memory buffers fill.

Back Pressure flow control is typically used in half duplex mode to send a "collision" signal to the
sending port (mimicking a state of packet collision) causing the sending port to temporarily stop

VLAN

The type of screen you see here depends on the VLAN Type you selected in the Switch Setup screen.

This chapter shows you how to configure 802.1Q tagged and port-based VLANs. See the General,

Switch and IP Setup chapter for more information.

7.1 Introduction to IEEE 802.1Q Tagged VLAN

Tagged VLAN uses an explicit tag (VLAN ID) in the MAC header to identify the VLAN membership of a frame
across bridges - they are not confined to the switch on which they were created. The VLANs can be created
statically by hand or dynamically through GVRP. The VLAN ID associates a frame with a specific VLAN and
provides the information that switches need to process the frame across the network. A tagged frame is four bytes
longer than an untagged frame and contains two bytes of TPID (Tag Protocol Identifier, residing within the
type/length field of the Ethernet frame) and two bytes of TCI (Tag Control Information, starts after the source
address field of the Ethernet frame).

The CFI (Canonical Format Indicator) is a single-bit flag, always set to zero for Ethernet switches. If a frame
received at an Ethernet port has a CFI set to 1, then that frame should not be forwarded as it is to an untagged port.
The remaining twelve bits define the VLAN ID, giving a possible maximum number of 4,096 (212) VLANs. Note
that user priority and VLAN ID are independent of each other. A frame with VID (VLAN Identifier) of null (0) is
called a priority frame, meaning that only the priority level is significant and the default VID of the ingress port is
given as the VID of the frame. Of the 4096 possible VIDs, a VID of 0 is used to identify priority frames and value
4095 (FFF) is reserved, so the maximum possible VLAN configurations are 4,094

7.1.1 Forwarding Tagged and Untagged Frames

Each port on the switch is capable of passing tagged or untagged frames. To forward a frame from an 802.1Q
VLAN-aware switch to an 802.1Q VLAN-unaware switch, the switch first decides where to forward the frame and
then strips off the VLAN tag. To forward a frame from an 802.1Q VLAN-unaware switch to an 802.1Q VLAN­aware switch, the switch first decides where to forward the frame, and then inserts a VLAN tag reflecting the
ingress port's default VID. The default PVID is VLAN 1 for all ports, but this can be changed.

7.1.2 Automatic VLAN Registration

GARP and GVRP are the protocols used to automatically register VLAN membership across switches.

VLAN 7-1

Dimension ES-3124PWR Ethernet Switch

GARP

GARP (Generic Attribute Registration Protocol) allows network switches to register and de-register attribute
values with other GARP participants within a bridged LAN. GARP is a protocol that provides a generic
mechanism for protocols that serve a more specific application, for example, GVRP.

GARP Timers

Switches join VLANs by making a declaration. A declaration is made by issuing a Join message using GARP.
Declarations are withdrawn by issuing a Leave message. A Leave All message terminates all registrations. GARP
timers set declaration timeout values.

GVRP

GVRP (GARP VLAN Registration Protocol) is a registration protocol that defines a way for switches to register
necessary VLAN members on ports across the network. Enable this function to permit VLANs groups beyond the
local switch.

Please refer to the following table for common IEEE 802.1Q VLAN terminology.

7.1.3 Port VLAN Trunking

Enable VLAN Trunking on a port to allow frames belonging to unknown VLAN groups to pass through that port.
This is useful if you want to set up VLAN groups on end devices without having to configure the same VLAN
groups on intermediary devices.

Refer to the following figure. Suppose you want to create VLAN groups 1 and 2 (V1 and V2) on devices A and B.
Without VLAN Trunking, you must configure VLAN groups 1 and 2 on all intermediary switches C, D and E;
otherwise they will drop frames with unknown VLAN group tags. However, with VLAN Trunking enabled on a
port(s) in each intermediary switch you only need to create VLAN groups in the end devices (A and B). C, D and
E automatically allow frames with VLAN group tags 1 and 2 (VLAN groups that are unknown to those switches)
to pass through their VLAN trunking port(s).

7.3 Introduction to Port-based VLANs

Port-based VLANs are VLANs where the packet forwarding decision is based on the destination MAC address
and its associated port.

Port-based VLANs require allowed outgoing ports to be defined for each port. Therefore, if you wish to allow two
subscriber ports to talk to each other, for example, between conference rooms in a hotel, you must define the
egress (an egress port is an outgoing port, that is, a port through which a data packet leaves) for both ports.

Port-based VLANs are specific only to the switch on which they were created.

The port-based VLAN setup screen is shown next. The CPU management port forms a VLAN with all Ethernet
ports.

7.3.1 Configuring a Port-based VLAN

LABEL DESCRIPTION

Setting Wizard Choose from All connected or Port isolation.

All connected means all ports can communicate with each other, that is, there are no virtual

LANs. All incoming and outgoing ports are selected (Figure 7-8). This option is the most flexible
but also the least secure.

Port isolation means that each port can only communicate with the CPU management port and
cannot communicate with each other. All incoming ports are selected while only the CPU
outgoing port is selected (Figure 7-9). This option is the most limiting but also the most secure.

After you make your selection, click Apply (top right of screen) to display the screens as
mentioned above. You can still customize these settings by adding/deleting incoming or outgoing
ports, but you must also click Apply at the bottom of the screen.

Incoming These are the ingress ports; an ingress port is an incoming port, that is, a port through which a

data packet enters. If you wish to allow two subscriber ports to talk to each other, you must define
the ingress port for both ports. The numbers in the top row denote the incoming port for the
corresponding port listed on the left (its outgoing port). CPU refers to the switch management
port. By default it forms a VLAN with all Ethernet ports. If it does not form a VLAN with a particular
port then the switch cannot be managed from that port.

Outgoing These are the egress ports; an egress port is an outgoing port, that is, a port through which a

data packet leaves. If you wish to allow two subscriber ports to talk to each other, you must define
the egress port for both ports. CPU refers to the switch management port. By default it forms a
VLAN with all Ethernet ports. If it does not form a VLAN with a particular port then the switch
cannot be managed from that port.

Static MAC Forward Setup

Use these screens to configure static MAC address forwarding.

8.1 Introduction to Static MAC Forward Setup

A static MAC address entry is an address that has been manually entered in the MAC address learning table. Static
MAC addresses do not age out. When you set up static MAC address rules, you are setting static MAC addresses
for a port. Devices that match static MAC address rules on a port can only receive traffic on that port and cannot
receive traffic on other ports. This may reduce unicast flooding.
